This blog is where Dan shares his views and opinions on emergency power supply systems.enTesting Generators with a Portable Load Bankhttp://ecmweb.com/blog/testing-generators-portable-load-bank
<div class="node-body blog-body"><p>As covered in my previous blog post, all diesel-powered generators should be loaded to at least 30% of their standby nameplate rating when exercised during their monthly test.</p></div>

<div class="node-body blog-body">We have not seen any empirical evidence demonstrating that increased testing of emergency power supply systems (EPSS) over and above what has been approved for inclusion in the consensus-based standard, NFPA 110, Emergency and Standby Power Systems, would improve reliability during power outages. </div>

<div class="node-body blog-body"><p><strong>Q.</strong> Is it true that a risk analysis can be performed in place of an arc flash study?</p>
<p><strong>A.</strong> An arc flash study is in fact a &ldquo;risk analysis&rdquo; if liberally interpreted using NFPA 70E definitions and OSHA regulatory language. Unfortunately, the term &ldquo;study&rdquo; has been misinterpreted and misapplied often.</p></div>

<div class="node-body blog-body"><p>Some insurance companies are now asking their clients to install 165&deg;F fusible links (valves) in the fuel oil supply (FOS) line between the main storage tank and day tank(s).&nbsp;In some cases, the companies are also asking for the links to be placed in the fuel oil return (FOR) line.&nbsp;The single reason for this is that &ldquo;if there were a fire in the generator room, the fuel supply to the generator(s) room would be shut down and therefore the chance of a &lsquo;burn down&rsquo; minimized.&rdquo;</p></div>

<div class="node-body blog-body"><p>The Department of Health and Human Services has published a 120-page proposed rule dated Dec. 27, 2013 (Vol. 78, No. 249). Within the proposed rule on pages 79173-4 at Section 482.15(e) &ldquo;Generator Testing,&rdquo; the Center for Medicare and Medicaid Services (CMS) has proposed a 4-hr generator test be performed EVERY 12 months. There is no mention of a minimum percentage of nameplate rating, minimum exhaust temperature, or a requirement that all automated transfer switches be transferred during the test.</p></div>
